That does make sense. Let's keep in mind that it'd be nice to have USB, but it'd also be a great effort. I'm sure it will eventually be added, but probably much later on.
No matter how great the effort, essentially someone has to actually do it, not much sense in just discussing the possibilities. I'd vote for SATA but if that also is a long way to go, good ol' PATA (IDE) will do.
